I have a shed stuffed full of tools for metalworking, woodworking, etc, but I'm now trying to take my first LGB loco apart. What tools do people recommend? obviously have some screwdrivers, but on my stainz to get the gearbox off I need to remove the hex head screw, and I don't have a tool for that. Do I attack it with pliers or is there a suitable toolkit I can get which will help? Advice appreciated.
